Website for Kerbal Space Program mods.
Quick overview:
- Install Python 3, node.js, virtualenv, PostgreSQL
- Set up aforementioned things
- Clone KerbalStuff repository
- Activate the virtualenv
- Install pip requirements
- Install coffeescript
- Configure KerbalStuff
- SQL
- Site configuration
Install the dependencies
You'll need these things:
- Python 3
- Node.js
- virtualenv
- PostgreSQL
Use the packages your OS provides, or build them from source.
Set up services
Do a quick sanity check on all of those things.
$ python3 --version
Python 3.4.1
$ node --version
v0.10.29
$ npm --version
1.4.14
$ pip --version
pip 1.5.6 from /usr/lib/python3.4/site-packages (python 3.4)
$ virtualenv --version
1.11.6
$ psql --version
psql (PostgreSQL) 9.3.4
YMMV if you use versions that differ from these.
I'll leave you to set up PostgreSQL however you please. Prepare a connection string that looks like this when you're done:
postgresql://username:password@hostname:port/database
The connection string I use on localhost is this:
postgresql://postgres@localhost/kerbalstuff
KerbalStuff needs to be able to create/alter/insert/update/delete in the database you give it.
Clone KerbalStuff
Find a place you want the code to live.
$ git clone git://github.com/SirCmpwn/KerbalStuff.git
$ cd KerbalStuff
Activate virtualenv
$ virtualenv --no-site-packages .
$ source bin/activate
If you're like me and are on a system where python3 is not the name of your
Python executable, add --python=/path/to/python3 to the virtualenv command to fix that.
pip requirements
$ pip install -r requirements.txt
CoffeeScript
# npm install coffee-script
$ coffee # Sanity check, press ^D to exit
Configure KerbalStuff
$ cp alembic.ini.example alembic.ini
$ cp config.ini.example config.ini
Edit config.ini and alembic.ini to your liking.
Postgres Configuration
Depending on your environment, you may need to tell postgres to trust localhost connections. This setting is in the pg_hba.conf file, usually located in /etc/postgresql/[version]/main/. An example of what the config should look like:
local all all trust
host all all 127.0.0.1/32 trust
host all all ::1/128 trust #may or may not be needed for IPv6 aware installs
Site Configuration
What you do from here depends on your site-specific configuration. If you just want to run the site for development, you can source the virtualenv and run
python app.py
To run it in production, you probably want to use gunicorn behind an nginx proxy. There's a sample nginx config in the configs/ directory here, but you'll probably want to tweak it to suit your needs. Here's how you can run gunicorn, put this in your init scripts:
/path/to/KerbalStuff/bin/gunicorn app:app -b 127.0.0.1:8000
The -b parameter specifies an endpoint to use. You probably want to bind this to
localhost and proxy through from nginx. I'd also suggest blocking the port you
choose from external access. It's not that gunicorn is bad, it's just that nginx
is better.
To get an admin user you have to register a user first and then run this (replace <username> with your username):
source bin/activiate
python
from KerbalStuff.objects import *
from KerbalStuff.database import db
u = User.query.filter(User.username == "<username>").first()
u.admin = True
u.confirmation = None
db.commit()
When running in a production enviornment, run python app.py at least once and
then read the SQL stuff below before you let it go for good.
We use alembic for schema migrations between versions. The first time you run the application, the schema will be created. However, you need to tell alembic about it. Run the application at least once, then:
$ cd /path/to/KerbalStuff/
$ source bin/activate
$ python
>>> from alembic.config import Config
>>> from alembic import command
>>> alembic_cfg = Config("alembic.ini")
>>> command.stamp(alembic_cfg, "head")
>>> exit()
Congrats, you've got a schema in place. Run alembic upgrade head after pulling
the code to update your schema to the latest version. Do this before you restart
the site.
